"I just want him to be forced to think about the magnitude of his poor decision.
"Really just hoping, once he knows that I know, he will be more likely to start backing away from her."
"Where I am not threatening anything,"
Re-read your quotes above. You are threatening him in a way. You are EXPECTING him to be a certain way to you. You WANT him to see he's doing wrong. You need to stop this type of thinking. It's pursuing.
No one can MAKE another person see something they don't want to. You have to let that part go. Find out what your rights are and protect yourself first legally.
If you really feel the need to tell him that you know, then I would tell him in a very straightforward, matter of fact manner. You don't have to tell him what you're going to do with the info. Hold your cards tight.

Emotion, yet peace. Ignorance, yet knowledge. Passion, yet serenity. Chaos, yet harmony. Death, yet a new life.
